Yes, that seems to be the way with these automotive quality assurance personnel!!! :wink:

Re: Any form of cooperation between NVH and GPS data?

It's an interesting question, but for the life of me, I cannot think why the GPS data in its own sense would make any difference to NVH analysis; almost everything of interest is available over an OBD tool, such as engine speed, load, coolant temp, etc. etc. So the way the car is being driven is ava...

Re: Vibration Analysis plugin failure

Thanks for the reply Steve. As long as the beta release is OK for this, I'm happy to stick with that until the stable releases have the feature. The installers probably need to take more account of problematic "older" releases these days, as the tools get older - and subsequently OS's get a longer h...

Vibration Analysis plugin failure

I'm not sure if I am the only one to have had a terrible time getting the latest Pico softwares to talk to the the NVH tools? As it stands, I can only see the NVH and Balancing tabs on my main laptop by using the Beta software 6.11.5, cannot see them in the stable 6.10.18, and then that was only aft...

Re: NVH kit accelerometer

Hi Steve (el. al.), I think that it must have been an early prototype from Gates that I had used in 1997. At the time, they were trying to make some progress in the OEM market, and a data-driven approach using such tools as described above was their way forward. The biggest problem I encountered dur...

Re: NVH kit accelerometer

If memory serves me correctly, these sensors are made up of two opposing microphones, attached to a C-shaped holder that is passed over the belt to measure it? Definitely no scope output in those days, but maybe a BNC on the sensor head that would allow a scope to be attached?

Re: NVH kit accelerometer

Steve,
Well, I didn't look at the finances too much. I just took the plunge. Lots of things to try now, if I can ever get the couriers to deliver here....!

Re: NVH kit accelerometer

Thanks Steve, I'm looking at the finances over the next couple of weeks. I'd like to do a bit of research anyway with the NVH kit, although it has to pay for itself over the next couple of years to be viable. I have one or two projects that may benefit from the application of this sort of tool. One ...

Re: NVH kit accelerometer

Steve, Many thanks for your reply. It answers so many questions. Not least, the validity in mounting the accelerometer by magnet to the seat fixings. Do you see the future "Chassis Ear" systems dovetailing into the NVH kit, or becoming a product in its own right? I'm still pretty keen to try an NVH ...

NVH kit accelerometer

I'm keen to explore the potential of the NVH kit, having seen the two (currently) published case studies. Has anyone got anything further to add regarding the potential of this equipment to isolate suspension-system clonks/rattles/etc. etc.? What I am assuming, because it is not explicitly stated in...
